JOURNAL-1B OX.

To all whom it may concern:

Be it known that I, WVILLIAM citizen of the United States, residing inthe city of Baltimore and State of Maryland, have invented a new anduseful Improve ment in Journal-Boxes, of which the following is aspecification.

This invention relates to improvements in journal boxes and moreparticularly to those used on railway locomotive tenders, assenger,freight and other car boxes Whic have the journal boxes located on theaxles outside of the wheels. It will be understood, however, that theinvention may be applied toother forms of journal boxes withoutdeparting from the spirit of the invention.

The improvements consist essentially 1n providing means for ventilatingthe interior of the journal boxes so that the stale air within thejournal box, external to the journal and bearing and alongside of same,is

E, Cxisr, a

change being caused by nozzles either of the direct or the induced drafttype and so 10* inside the journal box directly alongside o the journaland its bearing.

My invention consists more specifically in providing an air inlet and anair outlet communicating with the space inside of the joun nal boxdirectly around and about and alongside the outside of the journalbearing. These inlet and outlet orifices may be combined in a singlehole or orifice, or there may be two such orifices, one ip the Forwardand one in the rear side of the main portion of the journal box or ,twosets of such inlet and outlet holes arranged as desired on the journalbox.

urthermorflny improvements may consist in a structure wherein the coolor outside air passes directly into the journal box from the .front oradvance sideof the our- .nal box as thetrain is moving, and which willthus force the heated air within the journal box out at the rear side,and the cool thus replace the heated air. The ingress and egress of theair may be made through orifices directly in line with each other or theair may be made to follow a more tortuous course. On the other hand, theinlet and outlet orifices maybe so constructed that the cool air isdrawn into the journal box from the rear side of the mov- Speeificationof Letters Patent.

improvements may ;new car journal boxes, but that they may also bereadily applied on journal boxes already in use. caused to be drawn orforced out of the box i and replaced by fresh atmospheric air, this-Patented Jan. 6, 1914. Serial No. 664,769.

ing journal box, and the heated air drawn out at the front side, and inthis latter case, the use of a partial vacuum is employed, as will bebetter understood from the following description.

By the structure which I employ, a convthat is practically non-heating,and thus prevents the delays in operating trains caused by heated carjournals, and thereby materially reduces the cost of maintenance of thesame. It will also be obvious that my be applied not only to Myinvention furthermore consists in the novel lmprovements m the parts anddevices and in the novel combinations of parts and i devices hereinshown, described and claimed. cated that they will act upon the airspace In the drawing, wherein is illustrated one form of my invention,and the one which I now considerpreferable, Figure 1 is a side view of ajournal box showing my improvements. Fig. 2 is a vertical section of theimproved journal box, taken on the line 2-2 of Fig. 1, and looking inthe direction of the arrows, Fig. 3 is an enlarged detail, sectionalview taken on the line 33 of Fig. :2, looking in the direction of thearrows.

In the drawings, 10 represents the main portion of the journal box,which is provided with the usual lugs 11 and 12 on the sides thereof, bymeans of which the journal box is adapted to-be bolted to the car truck.On each side of t hmmain portion 10 of the journal box is a shel oroutside member 13, forming with the inner portion 14:, a. verticallyextending recess 14., as more clearly shown in Fig. 2, and having anopen ing 15 at the bottom thereof and also an opening 16 at the top. Theinnemportion 14 of the main member of the journal box is provided alsoon each side with a hole or orifice 17, which is located substantiallyopposite the hole or orifice 16 in the outer shell member 13, as shownin the drawings which are merely illustrative. Located between each ofthe outer portions 13 and the inner member 1a and preferably castintegrally therewith, is a Web or plane 18, each of said plates 18extending beyond the lower portions of the holes or recesses 16 and 17.

Preferably located in each of the orifices 17 is a screen 19, removablysecured therein as by means of t resilient coil member 20 adapted to beseated in a groove 21 in the inner portion 14' of the journal box, saidscreen 19 abutting a ledge 22 in the mem' her 14.

It Will be apparent that it the journal box is mounted on a train goingin the direction indicated by the arrow (0 in Fig. 2, that theatmosphe'ie pressure will be increased on the for vard or advance sideof the journal box, and that a current of air will flow in thedirection, as indicated by the small arrows 6. Such a flow of air willproduce a partial vacuum between the Web 18 and the inner portion 14;,thereby drawingthe heated air from the interior of the journa boxthrough the orifice 1?, which will then mix With the flow of air beingforced through the hole 16 and which. will then pass out at the hole 15.in this way, a partial vacuum is created in the interior oi the journalbox, which in turn induces un inflow of air through the orifice 17 onthe rear side of the journal box. it will be oh- YlOHS "when the traingoes in the opposite direction, that the low oii air through the journalbox will be in the reverse direction, or in other Words, that up n thetrain going in one direction, one hole or orifice errc as the inlet holeand the other for the m hole, and that upon going in :iuotldirection,jthe function of hen Any suitable form of cover or n be used'With the journal box.

It will be obvious that many he made in the details of my iuvemu outdeparting from the spirit theree motion,

all such changes are contemplhted L d hm tie scope oi the appended saidjournal box being prev another passageway commuthe interior of *1 namedpassageway, whe the interior of the box is tion induced by said air o;is in motion. 1
